Effect of carbon monoxide on rabbit cerebral arteries.
, 1994 Carbon monoxide produces relaxation in some peripheral arteries. Recently it has been suggested that carbon monoxide may be generated in brain tissue. In the present study we examined the hypothesis that carbon monoxide directly relaxes cerebral blood ...

Advanced Science, EarlyView.RCI is associated with functional suppression of oxytocinergic neurons in the PVN. Reduced PVNOXT neuronal activity contributes to altered sympathetic regulation involving the IML–sympathetic chain pathway, accompanied by changes in norepinephrine signaling at the BTI.

Heterogeneity in the response to dopamine of monkey cerebral and peripheral arteries
, 1983 In helical strips of monkey cerebral and mesenteric arteries contracted with prostaglandin F2 alpha, dopamine in low concentrations produced a moderate relaxation but in high concentrations produced a contraction from the level of relaxation.

Advanced Science, EarlyView.A distinct astrocyte subpopulation, enriched at the lesion border, drives CNS repair through enhanced ketone body metabolism. This process promotes neuronal survival and axonal sparing via CPT1A stabilization and H3K9bhb‐dependent epigenetic reprogramming, positioning astrocytic ketogenesis as a promising therapeutic target for tissue regeneration ...

AGING MEDICINE, EarlyView.Among 132 older adults, 13 had peripheral artery disease (PAD), identified using the ankle–brachial index. Over approximately 13 months, PAD was associated with increasing middle cerebral artery mean flow velocity, with a significant difference in left‐sided velocity change between groups.

Automatic labeling of cerebral arteries in magnetic resonance angiography
, 2016 In order to introduce 4D flow magnetic resonance imaging (MRI) as a standard clinical instrument for studying the cerebrovascular system, new and faster postprocessing tools are necessary.

Increased sympathetic innervation in the cerebral and mesenteric arteries of hypertensive rats
, 1990 The density of catecholamine-containing nerve fibers was studied in the cerebral and mesenteric arteries from normotensive Wistar–Kyoto rats (WKY), spontaneously hypertensive rats (SHR), and stroke-prone SHR (SHRSP) in the growing (SHR, WKY) and adult ...

Advanced Intelligent Systems, EarlyView.A unifying device–cardiovascular interface framework is presented to classify implantable cardiovascular technologies as intracardiovascular blood‐contacting systems or extracardiovascular tissue‐only and blood‐handling architectures. Cross‐class comparison across shared semiquantitative criteria, including blood‐contact burden, biomimicry ...
